Composite Stud Hole Insert for Horseshoe Thread Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing horseshoe stud systems face issues with thread deformation and dirt accumulation, making it difficult to fit or remove studs due to heavy loads and dirt ingress, which deforms threads and hinders the protection of stud holes.
Innovation Solution
A stud hole protection system featuring a cylindrical or conical stud hole core with a softer thread connection element made of polymeric materials like rubber or plastic, integrated with a screw driver slot for easy installation and removal, and gripping means to maintain shape under load, preventing thread deformation and dirt ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a foam plug is used to protect the threaded hole, then the threads are protected from dirt, but the foam plug deforms under heavy load and cannot support a metal stud
Solution Approach 1:
The protective plug combines a hard inner core (metal or hard plastic) that provides structural strength and load-bearing capacity with a softer outer layer (rubber or plastic) that protects the threads from dirt and deformation. This composite structure allows the plug to simultaneously resist both dirt ingress and heavy loads.
Solution Approach 2:
Different parts of the protective plug have different material properties: the inner core provides hardness and strength for load bearing, while the outer layer provides softness and flexibility for thread protection and dirt resistance. This local differentiation of material qualities resolves the contradiction between dirt protection and load bearing.
2Stability of the object's composition
If a hard protective plug is used, then the threads are protected from deformation, but dirt is pressed into the threaded holes and the plug cannot be removed
Solution Approach 1:
The protective plug uses a hard inner core to maintain thread integrity and prevent deformation, while the softer outer layer allows for easier removal and prevents dirt from being pressed into the threads. The differential material properties at different locations of the plug resolve this contradiction.
Solution Approach 2:
The softer outer layer acts as an intermediary between the hard inner core and the threaded hole, providing a interface that protects the threads from both deformation and dirt ingress while allowing for easier removal of the plug.
3Ease of operation
If the threaded hole is left open, then the stud can be easily fitted, but the threads deform under heavy load and become unusable
Solution Approach 1:
The protective plug serves as an intermediary that protects the threaded hole from deformation under heavy load while maintaining the capability for easy stud fitting. The plug remains in place during normal use to prevent thread deformation, but can be easily removed when stud replacement is needed.
Solution Approach 2:
The protective plug is installed in advance to prevent thread deformation before it occurs. This preliminary protective action ensures that the threads remain intact and usable for future stud fittings, resolving the contradiction between ease of operation and thread stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively protects stud holes from deformation and dirt, allowing for easy fitting and removal of studs while maintaining structural integrity under heavy loads, thus addressing the limitations of previous designs.
Implementation Method 1
The peripheral parts of the stud hole core are provided with a thread connection element of a softer material than the material of the stud hole core
Implementation Method 2
a clamping element in the form of an elastic sealing ring is inserted to avoid an unintentional locking of the sealing element
